Oh boy! Wet timing belts! Brightest idea ever. They are going great for Ford too!

Timing components at the rear of the engine that are inaccessible with the engine in the truck is probably the most genius of it all.



But if we are going down the rabbit hole,

I figured, or found out a few things on my car.
First thing is my Corvette style filter/regulator isn't regulating..

My fuel pressure at the rail is 100psi.

Another thing, Holley calls their tune files global configuration file, or GCF.
If I use the little 3.5" handheld touchscreen and wizard to build a base tune, it works, allows me to do the required tps reset but is much more basic.
If I use a GCF from the terminator x software off my laptop, there's much more I can do, but it fails the tps autoset every time.
So I used the handheld to create a baseline, then connected my laptop to modify it.
When I changed the actual fuel psi parameter from the 60psi baseline to 100, it still ran like garbage, but less garbage..

At this point I've pretty much decided I am going to pull the fuel tank, strip out all the lines and re-plumb the whole thing with AN lines and an adjustable regulator in the return.
While it's out, I will also need to cut the filler neck and extend it with a few inches of hose. Due to the pump, I had to shim the front of the tank and it puts the filler at a real pain in the aśş angle at the back bumper.

I feel your frustration with the fuel pressure regulator. I’ve tried 3 corvette style regulators. 2 cheap pos and 1 actual ac delco and none of them would keep my fuel pressure close to 60psi. Only thing I can figure is that my fuel pump just over powers them. I’m running a walbro 255lph in tank pump. My next step is basically the same as yours. I’m going to install a basic inline fuel filter and an adjustable pressure regulator under the hood. IMG_6076.jpegIMG_6077.jpeg
